* Make `r0::uiaa::ThirdpartyIdCredentials` an owned type and remove its `Incoming` equivalent
  * Previously, we had two fields of type `&'a [ThirdpartyIdCredentials<'a>]` and this kind of
    nested borrowing can be very annoying

  }
  ```

* Allow to construct the custom `AuthData` variant with `IncomingAuthData::new` and then call
  `IncomingAuthData::to_outgoing` on it.

  then call `IncomingLoginInfo::to_outgoing` on it.
* Move MSC2858 - Multiple SSO Identity Providers out of the `unstable-pre-spec` feature flag, this
  includes:
  * The `r0::session::get_login_types::{IdentityProvider, IdentityProviderBrand}` types
  * The `session::sso_login_with_provider::v3` endpoint

* Add unstable support for reasons for leaving rooms

# 0.11.2

Yanked since it depended on a version of ruma-api that had to be yanked too.

# 0.11.1

Yanked, wrong dependency version.

# 0.11.0

Breaking changes:

* Use `Raw<AnyInitialStateEvent>` over just `AnyInitialStateEvent` in the `initial_state` field

    clients and `endpoint::IncomingRequest` on servers, the other way around for responses.
  * When sending a request or response, you shouldn't have to clone things as much as before. Tip:
    Use clippy to detect now-unnecessary `.into()` conversions.
* Make most types non-exhaustive
  * This means you no longer can construct many of them using struct literals.
  * Instead, constructors are provided.

    useful.

      media::{get_content, get_content_as_filename, get_content_thumbnail},
      membership::join_room_by_id_or_alias,
      session::login,
  }
  ```
* Rename `r0::search::search_events::{RoomEventJsons => ResultRoomEvents}`. The previous name was an
  error introduced in a mass search and replace
* `r0::sync::sync_events::SetPresence` has been moved and renamed. Use `presence::PresenceState`
  from `ruma` or `ruma-common`.

* Change `ruma_events::AnyEvent` to `ruma_events::AnySyncRoomEvent` in
  `push::get_notifications::Notification`

* Fix `create_room` requests without an `initial_state` field failing deserialization
* Fix `sync_events` responses without a `device_one_time_keys_count` field failing deserialization

# 0.7.1

Bug fixes:

* Fix deserialization of `sync_events::Request`
* Fix (de)serialization of `sync_events::RoomSummary`

# 0.7.0

Breaking changes:

* Update ruma-api to 0.15.0
* Update ruma-events to 0.18.0
* Fix `r0::session::get_login_types`
* Add `allow_remote` parameter to `r0::media::get_content`

* Moved `r0::room::create_room::Invite3pid` to `r0::membership::Invite3pid`
* Replaced `user_id` parameter of `r0::membership::invite_user` with `recipient`
  to allow invitation of users by either Matrix or third party identifiers.
* Remove deprecated endpoint `r0::contact::create_contact` (deprecated in r0.6.0)
* Add lazy-loading options to `r0::filter::RoomEventFilter` (introduced in r0.5.0)
* Change type for `limit` request parameter of `r0::context::get_context` from `u8` to `Option<js_int::UInt>`
* Use `std::time::Duration` for appropriate fields on several endpoints:
  ```
  r0::{
      account::request_openid_token,
      keys::{claim_keys, get_keys},
      presence::get_presence,
      sync::sync_events,
